Mossbauer Effect Study of the Cations Distribution and its Influence on the Electric Field Gradient of the Cdx Co1-x Ferrite System

Abstract

In the ferrite system Cd,Co,_x Fe; 04 (X=0.0, O.I, 0.2, ....... , 1.0). it was found that the introduction of Co2'1' decrease the EFG at the octahedral B-site. This was attributed to the distributions of the different cations among the tetrahedral A and the octahedral B-sites. These distributions were completely calculated and found to follow four different formulas along the whole series of the system.
